Clubhook Squid (Moroteuthis robusta)

The Clubhook Squid is found only in the high North Pacific. It is often thought to be a Humboldt Squid when found on the beach, because of the similar large size. However, the Clubhook Squid gets bigger than Humboldt; it may reach a total length of over 4 m (12ft), with a mantle length of more than 2 m (6ft). Additionally, the Clubhook squid has ridges along its mantle, whereas the Humboldt squid has warts.
